Senior Avionics Embedded Software Engineer

Turning Space into a Transportation Layer for EarthWho We Are: Inversion builds advanced reentry systems to deliver next-generation capabilities from space. Our mission is to make Earth radically more accessible by turning Low-Earth Orbit into an on-demand logistics domain. We see space not as a destination, but as a platform — one that unlocks unprecedented speed and global reach. Our spacecraft are designed to deliver payloads anywhere on Earth in under an hour, operating through extreme reentry conditions and landing with high precision. These systems open the door to new ways of testing, delivering, and operating at hypersonic speeds. Inherently dual-use, our technology is built to meet urgent national security needs while laying the groundwork for future commercial applications. Backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, and working with partners such as the U.S. Space Force and NASA, Inversion is pushing the boundaries of what’s possible in space-based defense and logistics. What You'll Do  As a Senior Embedded Software Engineer at Inversion, you will report directly to the Manager of Arc Vehicle Avionics. In this role, you will own the development, testing, and deployment of highly reliable, low-latency flight software that runs on Arc’s vehicle avionics hardware. You will design and implement safety-critical code for microcontrollers, power distribution units, flight computers, and communication systems. Operating with high autonomy, you will bridge the gap between hardware and software, debugging boundary-level issues, establishing embedded coding standards, and ensuring our flight processors execute flawlessly through extreme reentry environments.  Key Responsibilities  Design, develop, and maintain high-reliability, real-time embedded software in C/C++ for Arc flight computers, microcontrollers, and actuators.  Architect and implement low-level device drivers for communication protocols including SPI, I2C, UART, CAN, Ethernet, and RS-422.  Own embedded software modules end-to-end, from early requirements definition through testing, qualification, and vehicle-level flight operations.  Bring up new avionics hardware platforms, debugging complex hardware-software boundary issues using JTAG, logic analyzers, oscilloscopes, and packet sniffers.  Integrate and validate embedded code using software-in-the-loop (SIL) and hardware-in-the-loop (HIL) test environments.  Perform rigorous code reviews, establish technical standards, and mentor junior embedded engineers on the team.  Collaborate closely with the core Flight Software and Simulation teams to align vehicle autonomy, telemetry architectures, and GNC algorithm execution.  Required Qualifications  Bachelor’s degree in Computer Engineering, Computer Science, Electrical Engineering, or equivalent technical experience.&nbs...
